1 Claim.

This invention relates to machines used for drying hair, and as now commonly employed in beauty salons, and in accordance with the present invention, a machine is provided whereby a considerable number of customers may be accommodated at the one and the same time and further, whereby to each head may be directed heated air at the desired temperatureand under the desired pressure.

Further, in accordance with the present invention a hair drying machine is provided which consists of comparatively few parts, will not detract from the" furnishing of the beauty salon,

and which will permit of the customer sitting at.

ease during the drying of the hair.

The invention together with its numerous ob- Jects and advantages will be best understood from a study'of the following description, taken in connection with the accompanying drawings wherein:

Figure 1 is an elevational view of the machine, the same being shown installed.

Figure'2 is an end elevational view thereof.

Figure 3 is a vertical sectional elevational view through a portion of the machine.

Figure 4 is a fragmentary vertical sectional view taken substantially on the line 4--4 of Figure 3.

Figure 5 is a vertical sectional view through an individual air discharge nozzle and the portion of the conduit connected therewith.

In carrying out the present invention, there is provided a floor designated by the reference character 10, the same comprising among other parts an air chamber 11 within which is arranged a blower fan 12 driven from a motor 13. The blower chamber 11 is of course provided with a suitable lateral inlet thereofwith an air outlet 14. Driving from the top of the blower casing is a pair of vertical conduits 15, 16 registering at their lower ends with the outlet 14. Each of the conduits 15, 16, at their upper ends merge into horizontal extensions 17, 18 disposed a considerable height from the floor so as to permit a number of customers being seated therebeneath in chairs 19 arranged and provided for such pur- Atsultable intervals, each of the conduits 1'7, 18 isconnected with a discharge nozzle 20.

'60 Each discharge nozzle 20 comprises a pair of parallel pipes or branches 21, 22 connected at their upper ends with the conduit branches 1'7,

nected to the lower ends of the pipe or tubes 21,

while the depending branch 22a of the chamber has connected thereto one end of a head cloth or sack 23 adapted to be disposed over the head of the customer in a manner well own in the art. 60.

Each of the vertical pipes 21, 2, at their lower ends are provided with a manually operable valve- 24.

Suitably mounted adjacent the lower end of the vertical conduit is a combustion chamber 25 that is open at its bottom, and which has extending across its open bottom, a plurality of gas burners 26 fed from a suitable source of supply in any suitable manner. The chamber 25 is also open at one side, and at said open side is suitably connected with the proximate side of the conduit 15.

Arranged in the conduit 15 is a plurality of vertical tubes 27, which at their lower ends are provided with lateral inlets 27a communicating with the combustion chamber 25. The upper ends of the tubes 27 project through the top of the proximate end of the horizontal conduit section 18 and projecting through the lower end of a flue pipe 28. i

As is thought apparent, the gas fumes, and the products of combustion will pass upwardly through the tubes 27 to discharge through the, flue pipe 28 and the cold air passing upwardly through the conduit 15 by contact with the tubes 27 will be heated.

Thus it will be seen that heated air will be conveyed to each nozzle 20 through the medium of theconduits l5 and 18 and to each nozzle 20 cold air will be supplied from the blower through the conduits 16 land 17. The hot air passing through the conduit 18 will also pass downwardly of the pipes 21, while the cold air from the conduit 1'7 will pass downwardly of the pipes 22. In using each nozzle, the valves 24 are properly adjusted for the feeding of the warm and cold air to the mixing chamber 23 and the air mixed in the chamber will discharge therefrom at the desired temperature on to the head of the customer. Obviously by adjusting the valves 24 the desired proportionate amount of cold and warm air may be-mixed for obtaining the'desired temperature of air supplied to the head.

Even though we have herein shown and described the preferred embodiments of our invention, it is to be understood that'we do not wish to limit ourselves to the precise details of construction, combination and'arrangement of elements as herein shown and described, but claim all such forms of the invention to which we are outlet and branches connecting the outlet with the conduit extensions, valves in the branches of the nozzles, a lateral combustion chamber at the lower end of one of the vertical conduits, burners arranged in the combustion chamber, and a plurality of flues disposed vertically in said one conduit and connected at their lower ends with the combustion chamber.
